FOUNTAIN -PEN.

Specification of Letters Patent.

Patented Oct. 19, 1920.

Application led March 13, 1919'. Serial No. 282,273.

To all whom t may concern: y

Be it known that I, HARRY W. I DIQKERS, a citizen of the United States, residing at in the county of Cook and of Illinois, useful Improvements in Fountain-Pens, of

specification. The invention relates to improvements in fountain pens.

One of the objects of the invention is to provide .anewfand improved means for attaching a holding. clip to the outer pen cap.

Another Objectis to provide a means, in association with the clip, into the pen barrel for collapsing the ink 'sack in self filling pens.

specific o b3ects of my invention will become readily apparent to persons skilled in the art from a consideration of the specification when taken in conjunction with the drawings, where- 1n Figure 1f is an elevation of a self filling pen embodying my invention.

Fig. 2 is a longitudinal central. section taken on line 2 2 of Fig. 1. i

Fig. 3 is a transverse section taken on line 3-3 of Fig.- 2.

Fig. 4 is a perspective view of the pin to be attached to the clip and used for the purpose of collapsing the ink sack.

In all the views the same reference characters are employed to indicate similar parts..

5 is the ordinary barrel of fountain pen ,ii-o vided with a pen point 6 at one of its ends and provided with screw threads 7 engaging threads 8 of the outer inclosing cap 9.

Self filling pens are provide-.i with a ccl lapsible ink sack 10, usually made of rubber, and overlying the sack, within the barrel 5, is a iiexible return strip 11 so that when the strip is pressed inwardly, the sack is collapsed and the resiliency `of the sack. causes it to become again expanded, thereby drawing ink into the sack in the usual manner. An opening 12 is made through the wall of the barrel for insertion of means for depressing the spring clip 11 and 13 shows the means for connecting one end of the clip to the barrel.

Located in the outer cap 9 is an inner cap 14, usually employed for more 'completely sealing thepen when the parts 5 and 9 are screwed together, at 7 and 8. The inner cap 14 is a usual part of a pen, and re- State" have invented certain new and vfor introduction the pin 22 may main'sfpermanently in the position shown in Fim 2, when the pen parts are assembled in finished condition.

I use the inner cap 14: as a means for holding the clip 15 in place. The outer cal.` 9 is perforated, as at 16, for entrance of the shank 17 of the clip. One side of the wall of the inner cap 14 is cut away, as at 18, to permit-tlie inclusion of the shank 17 between the inner and outer caps. The

clip 15 is bent, as at 19, so that tli'e mainy portion 20, thereof, will lie substantially parallel with the outside surface of the cap 9. The clamping tongue 20 of the clip, is provided with downturned ears 21, between which is pivoted the pin 22. The elongated end of the pin is substantially round, so that it may be inserted in the perforation 12, of the pen barrel. A pivot pin 23 passes through the downturned ears 21 and the thicker portion 2e, ofthe pin, which is provided with fiat sides 25 and 26. When the pin is iii a horizontal position, as shown in Fig. 2, the spring 27 bears against the fiat side 26 and yieldingly holds the pin in the position shown. line position, shown in Fig. 2, the spring 27 bears against the flat side 25 and yieldingly holds it in this position. When the pin is in this position, and the cap is removed from the barrel ofthe pen, then be inserted in the perforation 12 for the purpose of collapsing the ink sack 10. When the pin 22 is in horizontal position it is out of the way, but is always ready and convenient for the purpose de scribed.

A new clip can conveniently bc placed in position by removing the inner cap 14 and placing the shank 17 of the clip in the opening 16 and then replacing the inner cap.

While I have herein shown a single embodiment of my invention, for the ypurpose of clear disclosure, it is manifest that many changes may be made in the generaly arrangement and configuration of the parts within the scope of the appended claims.

I-Iaving described my invention, what I claim is 1. A fountain pen cap having a pocket clip secured thereto, and a pin pivoted to said clip and movable to two positions in one of which it may be inserted into an opening in the barrel of the pen to compress the ink sack therein.

2. A pocket clip having a shank and a `When it is in dotted clamping tongue with a slot intermediate clip secured thereto, and a pin pivoted t0' said shank and tongue; a pin, pivoted in said clip and for insertion into the barrel said slot, and a spring to yieldingiy retain of the pen to compress the ink sack therein. 10 the pin in a position substantially parallel In testimony whereof I hereunto subwith the axis of the pen and substantially at scribed my name.
